Begin the lesson by introducing the term 'amphibian' and its Greek origin meaning 'double life'. Discuss how this relates to their life cycle, which starts in water and transitions to land.

Engage students with a brief discussion on the importance of amphibians as indicator species due to their sensitive skin, which helps monitor ecosystem health.

Introduce the three main groups of amphibians: frogs, salamanders, and caecilians. Highlight their physical characteristics and adaptations for living on land and in water.

Use the video 'All About Amphibians' to provide visual demonstrations of the life stages of frogs and explain their unique adaptations.

Facilitate a discussion on the role of amphibians in ecosystems. Encourage students to think about how their permeable skin makes them sensitive to environmental changes.

Watch the video 'Poison Dart Frogs' to explore the unique adaptations and ecological roles of these vibrant amphibians.

Organize a classification activity where students sort images of animals into amphibians and non-amphibians, reinforcing their understanding of amphibian characteristics.

Assign the 'Amphibians Fact Sheet' assessment to help students identify and understand amphibian characteristics, habitats, and reproduction methods.

Conduct a quick quiz to assess students' comprehension of the key concepts covered in the lesson, such as amphibian life cycles and adaptations.

Encourage students to reflect on what they learned about amphibians and their ecological significance. Discuss any questions or insights they have.

For a comprehensive review, assign the 'Review – Animal Classification' assessment to reinforce students' understanding of animal classification, including amphibians.
